13. TESTS
Activiating the thruster when the boat is out of the water, is not advised under
any circumstances.
Tests must be carried out with the boat in the water, the battery(ies) charged at
100% and in charge, and the engines running.
The maximum continuous operating runtime corresponds to S2-3mn norm.
However, this can be affected by the ambient temperature.
14. ELECTRICAL MEASUREMENTS
In normal “usage” mode, i.e. thrusters running, boat in the water, with fully charged
batteries under ongoing charge (alternator), electrical measurements should be made at
the following points:
At the batteries
At the battery cut-off switch
At the fuse
At the electric motor’s connections
At the power supply arriving at the thruster control box
These measurements will enable you to detect voltage drop.
NOTE: the voltage reading between the motor’s negative and positive connections
should be approximately 10.5V for 12V models or 22V for 24V models during
operation.
The cumulative effect of voltage drops at these points can severely impair the
thruster's performance.
Should the voltage measured be too low, the following points need checking:
Are the batteries of sufficient capacity ?
Are the batteries good quality?
Are the batteries sufficiently charged?
Are appropriate cable sections being used?
Are the connections sufficiently tightened?
15. OPERATION
With the control system circuit breaker/ switch and manual battery isolator switched on:
Switch on the control panel, as previously described in the manual.
Push the red button or incline the joystick to the left and the boat moves to the left.
Push the green button or incline joystick to the right and the boat moves to the right.
If, during tests the boat moves in the wrong direction, change around the blue and the
brown wires on your power relay.
When manoeuvring remember that the boat’s momentum continues after you release the
joystick / button, therefore remember to release the control prior to reaching your desired
position.
Care must be taken not to use the thruster in areas where there may be people
swimming or floating debris.
Maximum running time: 2-3 min (depending on ambient temperature).
